SEX HAS MOVED ON. AGAIN. WHEN EL JAMES INADVERTENTLY CAUSED a run on provincial La Senza stores with the invention of Christian Grey, she probably didn’t appreciate the voraciousness of the sexual appetite she had awakened. Ultra-sensory sex, an underground trend now forging its way into the mainstream, is picking up where spank paddles left off.

When the lights are off, hyperstimulation can take the form of extreme heat, chill, pain or shock. Faced with such sensations, “the body first considers whether its about to be harmed,” says Jim Pfaus, professor of Psychology and Neuroscience at Concordia University, “because the nervous system is driven strongly in anticipation of distress.

Once it has eliminated danger, it serves up a rush of adrenaline.” And that means sex of higher intensity with heightened payback. Harness the fear, unleash the hormones and introduce her to a range of sensations she never knew existed.

Ice Play

There are many reasons to keep your icebox well-stocked other than the obligatory pre-date VTs. Intense cold creates an intense skin-tingling sensation as blood forces vasodilation, the dilating of the veins as her body tries to warm up. “Dopamine and noradrenaline are released when we vasodilate,” says Pfaus.

“The effect is heightened when the sensation is unexpected, meaning blindfolds can be sex toys in their own right.”

Crack open the ice as soon as things start to get heated. Or consider a vibrating ice massager, – essentially a sub-zero vibrator, it adds to the sensory thrill and stops you from feeling like an teenager with a full tray of ice cubes and a sopping wet sofa.

Electrolysis

When you apply an electric current directly to a motor nerve, it causes the muscle to contract. (Think of it as a mini-orgasm.)

In this case, the current also stimulates the sexual nerves as well as contracting the body, multiplying your orgasm.

Strap on the pads to both your bodies. “Sharing electrosex signals turns your bodies into electrodes, so you and your partner will feel tingles where your bodies touch one another,” says sex educator Hella Walkington.

Hot Wax

Your belle will be waxing lyrical tomorrow if you pull this one off, because candles come with a double dose of chemical love.

From the moment you light the wick, both of your bodies begin their hormonal arousal. The anticipation of high heat meeting skin releases dopamine and noredrenaline, which, again, prepare it for pain. As soon as the liquid wax hits skin, the adrenaline starts to rush.

Introduce the wax when you’re 10 minutes in to foreplay. Your nerve endings will be hyperaroused, meaning more of a rush.

Just make sure you use massage candles made with soy wax. “When you pour, it should turn to oil and stay warm, not scalding,” says Allison England of Coco de Mer. The wax activates a pulse of psychoactive opioids, creating a double whammy of pleasure and pain.

Clamping

The most important thing to know about clamping is that it’s the release that creates the sensation, not the pressure itself. So don’t go in too hard! Bondage expert Midori explains: “Temporarily restricting blood flow creates a flood of sensory feeling when the blood flows back into the skin – plus the psychological sensation of relief.”

Before you attach the clamp to the skin, test it for comfort by attaching it to the fleshy bit between your thumb and forefinger. Even then, save this one until you’re well in the throes of sex.
